METHOD or CONNECTIING THE HAMMER WITH THE CYLINDER or A REVOLVING FIRE-ARM.

Specification forming part of Letters Patent No. 6,669, dated August 28, 1849.

Be it known that I, EDWIN WEssoN, of Hart- Cylinders; and I do herebv declarethat the following is a full, clear, and exact description of the principle or character which (listinguishes it from all other things before known, and of the usual manner of making, modifying, and using the same, reference being had to the accompanying draw1ngs,-1n wh1chis the gearing which would be employed in a three-chambered cylinder, an end view of which is shown at Fig.4. Fig. 3 shows the clutch with a portion of the tumbler. y improvements in the construction of the ammer of the lock with the revolving cylinder of a firearm containing more than one mer and tumbler are drawn back to cook it the charge consist in placing within the lock oerbolt will enter one of the holes and clutch, so tain bevel-gear, hereinafterdescribed,by which as to cause the wheel d on the same arbor to I am enabled to producean equal leverage beturn; and this, by its connection, before, detween the hammer and cylinder throughout scribed, with the wheel 6, causes the cylinder their whole movement, and thus obtain a steadto revolve. By this arrangement the leverage too far, than any other method forefl'ectii'ig the same purpose with which I am acquainted. I described, when the arm is cooked. 0n discan also by the employment of the abovecharging it; the bolt in the recesskslips outof named gear, cause the cylinder to turn any the hole in the wheel d without turning it, in
